These thermocouples are used to measure outer termperature
in furnace tube walls.
Hot welding point can be supplied squashed in order
to be placed directly onto tube wall.
We advise to use preferently skin-points with welded
junction on a metalic plate (of appropiate type for
a possible weld with tube material) . in this way, the
plate will be welded to the tube, which is an easier
operation than directly welding the junction.
Determination of the number and diameter of expansion
turns is fundamental for the duration of a skin-point.
it is necessary to know the maximum expansion of each
tube planes related to the walls, as well as operation
temperatures. the material type of the sheath is selected
depending on the ambient conditions (oxydant or reductor,
as well as temperature, it will be tested in previous
